Convergence problems when using Harmonic Balance simulation in ADS

Hello,

I have a little problem regarding the simulation of an amplifier with a driver. The thing is that the simulation terminates due to convergence problems. I have tried many options, like changing the solver, etc.
Now I thought, that it may be possible to simulate the driver and the amplifier separately and combine the results in the end.
Does somebody know if this is possible and can describe me how to do so?
